Reference

The core edgedb object is a lightweight wrapper that manages the lifecycle of your event stream.

The SDK provides both callback-based and Promise-based APIs, so you can use it with callbacks, async/await, or Observables.

const stream = new RelayKit( apiKey: process.env.API_KEY, region: 'us-east-1' );

Each event flows through a series of transformation stages, with built-in support for filtering, mapping, and conditional routing.

Batching is automatic—control it via `batch(100)` or `batch({ size: 50, timeoutMs: 1000 })` to trade latency for throughput.

stream.pipe(map(e => e.data), buffer(100, 5000), flatMap(batch => fetch('/api/bulk',  body: JSON.stringify(batch) ))).catch(console.error);

Rate limiting is built in: configure token buckets, sliding windows, or adaptive limits that respond to backpressure.
